RACK OR HOLDER FOR VULCANIZING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 727,856, dated May 12,1903. Application filed September 13, 1902. Serial No. 123,291. (Numodel.)

To all whom it nmy concern..-

Be it known that I, WILLIAM R. SMITH, of Boston, in the county ofSuffolk and State of Massachusettshave invented certain new and usefulImprovements in Racks or Holders for .VulcanizingApparatus, of which thefollowing is a specification.

This invention relates to means for holdi ingelongated articles, such aslengths of metallic tubing which have been coated with a hard-dryingliquid composition, such as japan, the holder being adapted forinsertion in an oven in which the liquid coats of a series of articlesare to be baked or vulcanized.

The invention consists in the improved holder, which I will now proceedto describe and-claim.

Of the accompanying drawings,'forming a part 01' this specification,Figure 1 represents a perspective view of a holder embodying myinvention. Fig. 2 represents a vertical sectional view of the same.Fig.3 represents a perspective view of a portion of the base or bottomhead of the holder. Fig. 4 represents an enlargement of a portion ofFig. 2.

The same reference letters indicate the same parts in all the drawings.

In the drawings, a represents a bottom head or base which is apreferably fiat metal plate of substantial thickness, having a series oforifices (0' extending through it from its top to its bottom surface. Onthe walls of said orifices are formed thin-edged ribs or wingsff, eachorifice having a set of wings, preferably three in number, although thenumber may be varied. Each set of wings f constitutes a rest for thelower end of elongated articles d, such as a length of tubing.

connects with the space between the wings, into which the lower end ofthe article d projects, and provides for the escape by drainage of anysurplus liquid that flows downwardly from the coated surfaces of thearticle (1.

b represents a top plate or head which is of substantially the same areaas the base a and is rigidly connected to the latter by a series' ofuprights c c, the head 5 being separated from the base a by a space ofsufficient height to receive the major portions of the articles d. Thetop head b is provided with a series of orifices e, each formed toloosely surround the upper end portion of one of the .cles bearing onthe rests and articles (I and permit endwise movement of the saidarticle. The orifices e correspond in number and position with theorifices a in the base a, so that a corresponding number of articles (Zmay be supported vertically and parallel with each other by the conjointat. tion of the rests in the base a and the walls of the orifices e inthe top head I). o

It will be seen that the thin-edged ribsf are adapted to support thelower ends of the articles cl, while affording the minimum area ofcontact with the coated surfaces of said articles. The ribs f arepreferably provided with inclined faces f, so that the actual contactbetween the articles (1 and the rests is limited to the angles formed bythe junction of the external surfaces and the lower ends 76 of saidarticles, as illustrated in Fig. 4. The orifices e in the top head b areof sufficient size to permit theinsertion of the articles by inqiningthe articles and sliding them upwardlyin the orifices c and thenswinging in their lower ends and depositing them on the ifibs'f. Meansare provided for suspending the holder and its charge of articles at andfor lowering the holder into and raising it from a body of the coatingliquid. Means 89 may also be provided for supporting the holder from anoverhead track, so thatit r 'r be readily moved into and out of aVulcan. ing-oven.

I claim A holder for elongated arti l lengths of tubing, comprisi heador base having a pl the lower ends of the artic ing composed of a groupof r1 having thin 90 edges arranged to bear on the lower end of one ofthe articles, the base having also drainage-openings communicating withthe spaces between the ribs for the escape of surplus liquid from thearticles, and secondly, a top head rigidly connected with the base andhaving a plurality of orifices formed to loosely surround the upper endportions of the artipermit endwise such as a bottom movement of saidarticles.

In testimony whereof I have aifixed my signature in presence of twowitnesses.

WILLIAM R. SMITH.
